CAS Latency CL22

  • 32 GB dual-channel kit expands multitasking headroom for demanding workloads
  • 3200 MT/s DDR4 speed with CL22 timing accelerates data throughput
  • Intel XMP 2.0 profile enables one-click overclock to rated frequency
  • 20 V operation reduces power draw by up to 40 %
  • Micron 42-year heritage and module-level testing ensure long-term reliability

Capacity and configuration

This kit provides 32GB of DDR4 memory in two 16GB UDIMM modules. It uses the standard 288-pin desktop form factor and runs at 3200 MT/s with CL22 timings at 1.20V. The modules are unbuffered, non-ECC and carry an Intel XMP 2.0 profile for automatic configuration.

System fit and alternatives

The kit suits desktop builds that support DDR4 3200 and can operate at 1.20V; it will downclock to 2933 MT/s or 2666 MT/s if the platform requires lower speeds. Systems that require ECC, registered modules or a different DDR generation should select alternative memory.

Installation notes

Installation follows the usual UDIMM procedure: align the notch, press firmly until the retention clips engage, and enable the XMP profile in the firmware if the board supports it. Common issues include the memory running at a lower default speed until the profile is activated or a mismatch when mixing with modules of different timing or voltage.

Questions about this item

Will this kit work if my motherboard only supports DDR4 2666 MT/s?

Yes, the 3200 MT/s modules can downclock to 2666 MT/s or 2933 MT/s to match the motherboard's maximum supported speed.

Does the kit require manual BIOS changes to reach 3200 MT/s?

The kit includes an Intel XMP 2.0 profile; enabling XMP in the BIOS will set the rated 3200 MT/s speed and CL22 timings automatically.

Are these modules compatible with a standard consumer desktop board?

They are 288-pin UDIMM, unbuffered, non-ECC, 1.20 V modules — the standard form factor for consumer desktop DDR4 motherboards.
